Linux device drivers

Drivers are not same on Windows as they are on Linux.
however ,under some circumstances, Windows device drivers can be loaded into a Linux kernel.

Drivers can be complied into the Linux kernel or as seperate modules.
If they are modules, they can be (un)loaded on demand.

to find a specific driver , use grep , examples :
find /lib/modules/$(uname -r)/kernel/ -name '*.ko' | grep 'ax88179'
find /lib/modules/$(uname -r)/kernel/ -name '*.ko' | grep 'usb'

or replace the {kernel-version} after /lib/modules with your running version :
use uname -a # to see which version is running right now.
